A rectangular loop of wire has area A. It is placed perpendicular to a uniform magnetic field B and then spun around one of its sides at frequency f. The maximum induced emf is: BAf 4TTE BAf BAf/2π 2πT BAf

Near San Francisco, where the vertically downward component of the earth's magnetic field is 5.7 x 10-5 T, a car is traveling forward at 30 m/s. The width of the car is 2.3 m. Find the emf induced between the two sides of the car. If positive charge accumulates on the driver's side, the enter the emf as a positive number. If negative charge accumulates on the driver's side, the enter the emf as a negative number. Number i Units

Magnetic flux increases from 0 to 2 Tm2 in one turn conducting loop within 0.5s. What is the induced emf in the loop? 0.5 V 2 V 0.3 V 4 V 1 V

An emf is induced by rotating a 1070 turn, 20.0 cm diameter coil in the Earth's 4.95 ✕ 10−5 T magnetic field. What average emf (in V) is induced, given the plane of the coil is originally perpendicular to the Earth's field and is rotated to be parallel to the field in 10.0 ms?
